Cordierite and Foitite Chemical Formula

While comparing Cordierite and Foitite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Cordierite and Foitite chemical formula.

  • Chemical formula of Cordierite- Mg2Al4Si5O18
  • Chemical formula of Foitite- Na x[Fe2+2(Al,Fe3+ )]Al 6(BO 3) 3Si 6O 18(OH) 4Anthony et al , Handbook of mineralogy (2001)

Cordierite and Foitite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cordierite and Foitite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cordierite and Foitite Optical Properties during the identification of gemstone. Specific gravity of Cordierite is 3.17 whereas that of Foitite is 3.17.
